Method Detail

getAlgorithm

public String getAlgorithm()

Description copied from interface: Key

Returns the name of the algorithm of this key. If the algorithm is unknown, null is returned.

Specified by:

getAlgorithm in interface Key

Returns:

the name of the algorithm of this key or null if the algorithm is unknown.

getFormat

public String getFormat()

Description copied from interface: Key

Returns the name of the format used to encode this key, or null if it can not be encoded.

Specified by:

getFormat in interface Key

Returns:

the name of the format used to encode this key, or null if it can not be encoded.

getEncoded

public byte[] getEncoded()

Description copied from interface: Key

Returns the encoded form of this key, or null if encoding is not supported by this key.

Specified by:

getEncoded in interface Key

Returns:

the encoded form of this key, or null if encoding is not supported by this key.

getParams

public DHParameterSpec getParams()

Description copied from interface: DHKey

Returns the parameters for this key.

Specified by:

getParams in interface DHKey

Returns:

the parameters for this key.

getY

public BigInteger getY()

Description copied from interface: DHPublicKey

Returns this key's public value Y.

Specified by:

getY in interface DHPublicKey

Returns:

this key's public value Y.

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Overrides:

hashCode in class Object

Returns:

this object's hash code.

See Also:

Object.equals(java.lang.Object)

equals

public boolean equals(Object o)

Description copied from class: Object

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Overrides:

equals in class Object

Parameters:

o - the object to compare this instance with.

Returns:

true if the specified object is equal to this Object; false otherwise.
